Pl suggest the most reliable site for statutory rules like that of Leaves applicable in shop and Establishments Act with more than 20 employees in Delhi, Haryana etc?

Hello friends, where can I find the most reliable statutory rules such as those governing leaves applicable in the Shop and Establishments Act for entities with more than 20 employees in Delhi, Haryana, etc.? Which site is the most reliable and easily understood? Some sites are not updated. I kindly request you to share both government and private sites/links. TIA :)

The most reliable website for notifications relating to establishments is the official website of the labor department of the state concerned. Please follow that.
